to help troubleshoot, check server access log for the image in question and verify if it was served partial and fully served on browser refresh.
I did a force reinstall already and the issue still persists. I checked the log files and the file is actually served partially for some unknown reason. This is a static image. I have exactly the same problem that the thread starter has. I am thinking it must be a bug that needs fixing, oh btw i am on Cpanel/WHM 126.96.36.199
